The Design Of Automatic Kilowatt_hour Meter Reading System

With the development of electron and computer ,automatic meter reading system(AMRS) will be put into reality.This article aims at kilowatt_hour meter for house or for office. banded the working principle and the real working conditions of mechanical kilowatt_hour meter, I designed an automatic kilowatt_hour meter reading system. The strong point of this system is: low cost, stable working and easy to install. The article gives an all-around design of this system. It expatiates on designs of data collection, data communication mode and computer software. It introduces the generality and the reliability of this system in brief. During the study of automatic kilowatt_hour meter reading system,I solved the following technology of key importance: (1) Finished data convertor without rework the kilowatt_hour meter. (2) According to power supply ,I designed a storage mode consistent with the work of kilowatt_hour meter. (3) Designed communication network and communication control protocol which adapted to the automatic kilowatt_hour meter reading system. This paper finished the following works on the automatic kilowatt_hour meter reading system: (1) Finished the design of hardware and the design of software of the system forehead. (2) Finished the design of communication interface. (3) Briefly analysed how to communicate through electric power line. Applying ASK data modulation,I designed a new way of delay determinant to demodulate. And finished the design of data transceiver. (4) With the help of database management system(DBMS), I finished the design of synthetical management software of AMRS. (5) According to the designs, I finished the hardware and the software. And I tested the work of system. (6) Based on WEB , I designed model of remote reading and remote query, which will be perfected in the future.
